noble gases
Beryllium will have the highest. Down a group ionization energy decreases.

Carbon has the highest ionization energy in Group 4 of the periodic table. This is because as you move across a period from left to right, the ionization energy generally increases due to increase in effective nuclear charge. Among the elements in Group 4 (carbon, silicon, germanium, tin, lead), carbon has the highest ionization energy.
Beryllium is the group 3A element with the highest ionization energy.
The element with the highest first ionization energy in group 14 is carbon.
Helium (He) has the highest ionization energy, then Neon (Ne) Ionization energy increases as you go across a period from left to right. Ionization energy decreases as you go down a group. Therefore, elements in the upper right of the periodic table have the highest ionization energy.
The element with the highest ionization energy in Group 3A (Group 13) is usually thallium (Tl), followed by indium (In) and then gallium (Ga). Thallium has the highest ionization energy due to its partially filled d-orbital, which imparts extra stability.
Noble gases have the highest first ionization energies because they have a full valence shell, making it difficult to remove an electron. Within a period, ionization energy generally increases from left to right due to increasing nuclear charge.

The ionization energy decrease moving down in a group.
Nitrogen (N) is the group 15 element that can lose an electron most readily because it has the highest ionization energy within the group. This means that it requires the least amount of energy to remove an electron from a nitrogen atom compared to the other group 15 elements.
Imagine that one electron has already been removed from an atom, the energy used to accomplish this is the 1st ionization energy. Now more energy is needed to remove a 2nd electron. That is the 2nd ionization energy.
